LUBRIGANT DEMONSTRATO.

Application filed .Tune 1,

To all 'whom it may concer/n Be it known that I, HENRY A. NEALLEY, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Lubricant Demonstrators, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to lubricant demonstrators and particularly to devices for testing or demonstrating the qualities of graphites, greases, oils and the like.

In order that the principle of the invention may be readilyy understood, I have disclosed a single` embodiment thereof in the accompanying drawing, wherein- Fig. 1 is a plan view of a lubricant demonstrator embodying my invention;

Fig. 2 is a longitudinal vertical section upon the line 2-2 of Fig. 1; and

Fig. 3 is a transverse section upon the line 3 3 of Fig. 1.

The primary object of my invention is to provide a simple device, preferably readily transportable, for displaying and manually testing the qualities of lubricants, such, for

. example, as graphites, or fluent lubricants,

such as greases and oils, and preferably to permit two like devices one having lubricant applied thereto and one without lubricant, to be tested side by side. In carrying out this purpose of myhinvention, I preferably employ the following construction of parts to which specific embodiment of the invention, I am not, however, to be restricted, since the purpose thereof may be practiced by other devices or appliances.

Referring more particularly to the drawing, the base is represented at 1. This is desirably a piece of wood, though any suit-` able material may be employed. Thereupon I secure, as by screws, or I may form therewith, a suitable structure which is herein represented as a piece of sheet metal 2 bent or otherwise formed to provide a plurality of channels or tracks 3, 4. The metal which may be zinc, tin or any other suitable material, and which is desirably unpolished, is here shown as bent to pro-vide upright walls 5, 6, 7, 8, constituting the parallel opposing walls of the two channels or track ways 3, 4, and the outer wall 9, 10 parallel thereto. Desirably the channels or track ways 3, 4 are closed at their ends as by provid- 1922. Serial No. 565,277.

surfaces of the channels or track ways. If o desired, said bases 18, 19 may have upstanding sides 20, 21, 22, 23, as shown, and in i order to confine said members within the channels or track ways,`I provide any suitalble construction, as, for example, a plurality of suitably shaped metallic or other strips 24, 25, 26, secured to the sheet metal 2 between the channels or track ways as by suitable screws 27. I have herein repre-` sented the strips 24 and 26 as right angled and the strip 25 as flat but with inwardly bent edges, the construction being such as to prevent the displacement of the members 1S, 19 from the channels or track ways, but permitting them readily to be slid therein when manual -force is applied to any suitable part thereof, as, for example to the handles 28, 29. Obviously, if desired, the members 18, 19 maybe caused to slide by tilting the base 1 in a suitable manner.

The members 18,-19, are preferably of ,metalfand they may be of thefsame metal as that employed for the channels or track ways. If desired, I may provide a series of removable linings which may be placed within the channels 3, 4, as by removing the overlying strips 24, 25, 26, or by removing one of the endsll, 12. One purpose in providing this construction is that when the channels have become soiled by reason of the use of lubricant therein, a lining may be more quickly applied and in less time than would be occupied in thoroughly cleansing the channels. The channels, if desired, may be covered to prevent any undesired entrance of dust or other foreign substance, as

bythe provision at each end of the channels or track ways of stationary strips of celluloid or other transparent material, and intermediate longitudinal strips slidable with the handles.

In the use of my invention, a lubricant to be tested` is applied to one of the channels and the member therein is caused to slide back and forth upon the lubricated channel them in one of the channels and using,r another in another channel. lt may be desired in an unlubricated channel to place a slight quantity of dust to typify the operation of an unlubricated part.

While l have represented two channels, it is obvious that l am not restricted thereto, as obviously a greater or a less number of channels may be employed, and in any case. said channels may be of any desired length. lt will be readily understood from the foregoing' description that the entire appliance is of simple construction, but that it is'effective forthe purpose intended. It is readily transportable and may be readily used at exhibitions such as automobile shows where the interest of those in attendancevr at the show will be quickly gained by the described demonstration.

l-laving'thus described one embodimentfof myv invention, l desire it to be understood. that although specific terms are employed, they are used in a` generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims:

l.' A lubricant demonstrator for graphite, greases, oils and the like comprising a base provided with a plurality of channels having closed ends, and a freely slidable member positioned in each channel, and having,r manually graspable means for sliding said member and adapted to receive a slight charge of lubricant between its under surface and the surface of the channel, whereby the lubricating` quality of the applied lubricant maybe tested by such manual manipulation.

2. A lubricant demonstrator comprising' a base hwing` a pluralityof iiat parallel channels slightly spaced apart and having closed ends and sides` a manually manipulable sliding member adapted to be recei .fed in each of said ,Qjroovesand having' a flat under surface of relatively large area. positioned flat-wise in its channel and yadapte-d to receive a small charge of lubricant between its under surface and the surface of the channel whereby the quality of the lubricant may be tested by comparing the ease with which the members in the said grooves may be slid manually.

Il. A, lubricantdemonstrator ccanprisinc` a. base having; a relatively broad channel having' a flat bottom and coni'iningj walls, and a slidable member received in said channel having; manually graspable means for slidinn' said member, the under surface of said -member being` flat and of relatively large area and adapted to receive a slight charge of lubricant to be applied thereto or to the surface yof the channel, so that the quality'of the lubricant may be tested by the comparative ease with which the member may be slid after application of the lubricant.

a. A lubricant demonstrator comprising a base having relatively broad channel having; a bottom wall and confining side walls,

and a slidable member received in said channel having' manually graspable means for 'slidino' said member. the under surface of said member being of relatively large area and conforming' to the ybottom wall of the channel and adapted to receive a charge of lubricant to be applied thereto or to thesurfaceof the channel whereby the qualityof the lubricant may be tested by manually reciprocatingi said slidable member.

ln testimony whereof, l have signed my name to this specification.

HENRY A. NEALLEY.
